WMV to 3GP Converter
Processing entirely on your device — large files may take a moment.
Windows Media Video and 3GPP Mobile Video exist for different jobs: WMV is Microsoft’s Windows Media video format, still found in old recordings, webinars and screen captures. Rescuing old phone videos means converting 3GP to MP4 before the memories become unreadable.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the WMV format
WMV (Windows Media Video) is Microsoft's codec family, most commonly WMV3/VC-1 inside an ASF container. In its Silverlight-era heyday it delivered good quality at dial-up-to-DSL bitrates and DRM for Windows Media services. Today it survives mainly in corporate archives, old training videos and PowerPoint embeds from the 2000s.
Non-Windows playback was always its weakness and remains so: macOS and Linux need workarounds, phones and web platforms ignore it. Converting WMV to MP4 is the standard exit, and usually saves space at the same time.
+ Strengths
- ✓Good quality-per-bit for its era
- ✓Native Windows Media integration
! Limitations
- −Poor non-Windows and mobile support
- −Obsolete next to H.264
- −DRM variants are device-locked
About the 3GP format
3GP is the 3GPP mobile video format from the pre-smartphone era, designed for 2G/3G bandwidth: low resolution (typically 176×144 to 640×480), H.263 or baseline H.264 video, and AMR audio. Every early camera phone recorded in it, and MMS messaging depended on its small footprint.
It is strictly a conversion source today: pull the videos off an old phone, convert to MP4, and enjoy a resolution upgrade from better scaling alone. Quality expectations should stay low — the pixels were never there.
+ Strengths
- ✓Tiny files for its era
- ✓Plays on old feature phones
! Limitations
- −Very low resolution and quality ceiling
- −Obsolete; no modern platform wants it

Frequently asked questions
Is this WMV to 3GP converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for WMV to 3GP?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
Does converting WMV to 3GP re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
